It hides it but I need to re claim the space it occupies(the main reason I need to hide it)

Same with the application Menu , I can hide it but I don't re claim the space it occupies ???

Hello ,
 
I have been looking into your issue and usually there is no built-in functionality as it would contradict with the Micrsosoft Guidelines for creating Ribbons, which would in turn break the license agreement we have for providing proper ribbon design and behavior.

If you would like to go about and modify the XamRibbon outside its supported version, so that the ‘QuickAccessToolbar’ is invisible and reclaim the scape that it occupies, you can re-template the default template for the XamRibbon control. I would like to point out that removing the occupied by the QAT space would make the ‘ContextualTabs’ functionality disappear too. I am sending you a sample application(RibbonVisi.zip) where I have created a custom template that achieves the desired functionality, which you can use for a starting point, if you decide to make a custom template of your own.

If you have any other questions on this matter, feel free to ask.

I cannot loade your project , you are using Silverlight 5.0 libraries and we have not moved to 5.0 yet (client support issues)

I had to manually edit the project file and set all references back to SL4 versions.

this will give us just what I was looking for so thank you, but what was it exactly that you edited in the style?

Hello,

I am just checking if you require any further assistance on the matter.

Yes we are all set, your solution is what we were looking for

thank you!
